Mechanical Control is the physical removal of the stem and branches of
target vegetation by cutting, chopping or mowing.

Chemical Control is the selective use of herbicides applied to the
foliage, stems and/or root zone of target vegetation.

Natural Control is the science of working in concert with the biological
stages of plant succession and interspecies competition to limit the
establishment of undesirable vegetation.

Cultural Use of the Landscape is working in concert with the use of our
landscape for economic, agricultural, social and recreational purposes. These
are areas in which the man-made landscape changes the IVM management techniques
applied to existing target vegetation.
